Answer:

1915

Explanation:

formula for the nth term is

an = d times n + first term - d

an = n*d + a1 - d

find the difference between the numbers

it's 15 which is d

first term is a1 which is 415

a101 = 15 times 101 + (415 minus 15)

a101 = 1515 + 400

a101 = 1915

Answer:

1915

Explanation:

nth term = 15n + 400

term to term = 15

n = position

eg:

n=1

1x15=15 + 400 = 415

n=2

2x15=30 + 400 = 430

n=101

101x15= 1515 + 400 = 1915
