Question

Jonah sesquare started creating the following pattern in steps

Answer 1

Answer = the

According to the pattern he started with

The first term = 1

The common difference = 4

The nth term of a Arithmetic sequence =

Tn = a + (n - 1) d

Where a = first term , d = common difference, n = number of terms

a = 1, d = 4, and n = 15

T15 = 1 + (15 - 1) x 4

T15 = 1 + ( 14) x 4

T15 = 1 + 56

T 15 = 57
