Question

Tha 4term from the end of the a.p:7,10,13_______151?

Answer 1

Answer:

The ans is 142.

Step-by-step explanation:

The common difference = d = 3

So, by flipping the equation d becomes -3

So, Fourth last term = 151 - 3×3

(Here ×3 resembles moving three terms ahead)

= 151 - 9

= 142.

Answer 2

Answer:

142

Step-by-step explanation:

l - (n  - 1)d = required term

where, l = last term

n = no. of the term

d = common difference

151 - ( 4 - 1 )(3)

151 - 9 = 142
