What is the 32nd term of the arithmetic sequence where a1 = 12 and a13 = -60
Olin [163]

Answer:

The 32nd term of Arithmetic sequence is -174

Step-by-step explanation:

Given: a_1=12, a_{13}=-60

We are given two term of the Arithmetic sequence.

Formula:

a_n=a+(n-1)d

For  a_1=12

a=12

For a_{13}=-60

a+12d=-60

Using two equation solve for a and d

12+12d=-60

1+d=-5

d=-6

We need to find 32nd term

a_{32}=a+31d

a_{32}=12+31(-6)

a_{32}=12-186

a_{32}=-174

Hence, The 32nd term of Arithmetic sequence is -174
