The terms of the sequence are found by first putting n = 1, then n = 2, then n = 3 and finally n = 4 in the rule for the nth term = 2n. As follows:
n = 1 gives 2 × 1 = 2 n = 2 gives 2 × 2 = 4 n = 3 gives 2 × 3 = 6 n = 4 gives 2 × 4 = 8 |

The terms of the sequence are found by first putting n = 1, then n = 2, then n = 3 and finally n = 4 in the rule for the nth term = 2n -1. As follows (do the multiplication first THEN the subtraction):
n = 1 gives 2 × 1 - 1 = 1 n = 2 gives 2 × 2 - 1 = 3 n = 3 gives 2 × 3 - 1 = 5 n = 4 gives 2 × 4 - 1 = 7 |
The terms of the sequence are found by first putting n = 1, then n = 2, then n = 3 and finally n = 4 in the rule for the nth term = -n + 1. As follows:
n = 1 gives -1 + 1 = 0 n = 2 gives -2 + 1 = -1 n = 3 gives -3 + 1 = -2 n = 4 gives -4 + 1 = -3 |

The terms of the sequence are found by first putting n = 1, then n = 2, then n = 3 and finally n = 4 in the rule for the nth term = -5n. As follows:
n = 1 gives -5 × 1 = -5 n = 2 gives -5 × 2 = -10 n = 3 gives -5 × 3 = -15 n = 4 gives -5 × 4 = -20 |
The terms of the sequence are found by first putting n = 1, then n = 2, then n = 3 and finally n = 4 in the rule for the nth term = 4n + 7. As follows (do the multiplication first THEN the addition):
n = 1 gives 4 × 1 + 7 = 11 n = 2 gives 4 × 2 + 7 = 15 n = 3 gives 4 × 3 + 7 = 19 n = 4 gives 4 × 4 + 7 = 23 |

The terms of the sequence are found by first putting n = 1, then n = 2, then n = 3 and finally n = 4 in the rule for the nth term = n2. As follows:
n = 1 gives 12 = 1 n = 2 gives 22 = 4 n = 3 gives 32 = 9 n = 4 gives 42 = 16 |
The terms of the sequence are found by first putting n = 1, then n = 2, then n = 3 and finally n = 4 in the rule for the nth term = n2 - n. As follows (do the multiplication first THEN the addition):
n = 1 gives 12 - 1 = 0 n = 2 gives 22 - 2 = 2 n = 3 gives 32 - 3 = 6 n = 4 gives 42 - 4 = 12 |

The terms of the sequence are found by first putting n = 1, then n = 2, then n = 3 and finally n = 4 in the rule for the nth term = 6n. As follows (do the multiplication first THEN the addition):
n = 1 gives 6 × 1 = 6 n = 2 gives 6 × 2 = 12 n = 3 gives 6 × 3 = 18 n = 4 gives 6 × 4 = 24 |
The terms of the sequence are found by first putting n = 1, then n = 2, then n = 3 and finally n = 4 in the rule for the nth term = 4n - 1. As follows (do the multiplication first THEN the subtraction):
n = 1 gives 4 × 1 - 1 = 3 n = 2 gives 4 × 2 - 1 = 7 n = 3 gives 4 × 3 - 1 = 11 n = 4 gives 4 × 4 - 1 = 15 |
n = 1 gives 2 × 1 + 3 = 5
n = 2 gives 2 × 2 + 3 = 7
n = 3 gives 2 × 3 + 3 = 9
n = 4 gives 2 × 4 + 3 = 11
