Question

Find the sum of first 10 terms in the series in the series 2,5,8,11,14 . ln the above series find the 24 th term​

Answer 1

Answer:

155 and 71

Step-by-step explanation:

a= 2

d= 5-2= 3

24th term = a+23d = 2 + 23×3 = 2+69 = 71

Sum of first 10 term= n[2a+(n-1)d]/2

=10[2×2+(10-1)3]/2

=5[4+27]

=5×31

=155
