Question

can you guys help me find the first 5 terms of:

a1=16
an= an-1 + 14

Answer 1

Given: a1=16

an=an-1 +14

To find: First 5 terms

Solution:

an=an-1 +14

an-an-1=14

We know that, difference between two consecutive terms gives the common difference of the arithmetic progression.

so, an- an-1= d where, d is the common difference

here, we got d =14

a1=16

so, first 5 terms of the AP is: 16, 16+14, 16+(2*14), 16+(3*14), 16+(4*14)

=16, 30, 44, 58, 72
