Question

Which term of the AP 5, 8, 11,... will be 57 more than its 25th term?​

Answer 1

Step-by-step explanation:

let n term be 57 more than its 25 term

so,

a+(n-1)d= a+(25-1)d+57

5+(n-1)3= 5+(25-1)3+57

5+(n-1)3= 62+24×3

5+(n-1)3= 62+72

5+(n-1)3= 134

(n-1)3= 129

n-1= 43

n = 44

hence the term be 44
