Question

Algebraic expression of an arithmetic sequence is 8n+6
a ) find out first term and common difference?
b ) find out 27th term ?
c ) find out sum of (n+1) terms of this sequence?
d ) find out sum of 10 terms ?​

Answer 1

Step-by-step explanation:

◆ first term = 8+6 = 14

◆second term = 16 + 6 = 22

◆common difference = 22 - 14 =8

◆27th term = a + 26d

= 14 + 26(8)

= 14 + 208

= 222
