Answer:

the is your answer

the 50term is 149.

the sum of 50term is 3775.

Step-by-step explanation:

a=t1=2,t2=5

d= t2-t1

d=5-2

d=3

tn=a+(n-1)d

t50=2+(50-1)3

t50=2+(49)3

t50=2+147

t50=149

therefore the 50term is 149

Sn=n÷2[2a+(n-1)d]

S50=50÷2[2×2+(50-1)3]

S50=50÷2[4+(49)3]

S50=50÷2[4+147]

S50=50÷2×151

S50=25×151

S50=3775

therefore the sum of the 50term is 3775.
