Write down the first 5 terms of n squared + n

Alex73 [517]

Answer:

2, 6, 12, 20, 30

Step-by-step explanation:

To find the first 5 terms substitute n = 1, 2, 3, 4, 5 into the expression

n = 1 → 1² + 1 = 1 + 1 = 2

n = 2 → 2² + 2 = 4 + 2 = 6

n = 3 → 3² + 3 = 9 + 3 = 12

n = 4 → 4² + 4 = 16 + 4 = 20

n = 5 → 5² + 5 = 25 + 5 = 30
