Question

What is the 46th term of the arithmetic series 1, 8, 15, … ?

Answer 1

I don't know why, but I can never remember the formula for this

Answer 2

2(1)+(45)7

Answer 3

this is an arithmetic progression, and the formula for find an n term is : an = a1 + (n-1)d. so, an = a1[first term, so 1] + (n[number of terms, so 46]-1)d[7]. so:

an=1+(46-1)*7 -> an=1 + 45*7 -> an = 315.
